Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If network resources are statically allocated in traditional 5G networks, then network infrastructure is simplified, but resource allocation flexibility and adaptability to diverse application requirements deteriorate

Engineering Contradiction:
Improveresource allocation flexibilityVSAvoidnetwork architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the network into multiple virtual network slices, each tailored to specific application requirements (e.g., enhanced mobile broadband, ultra-reliable low-latency communication, massive machine type communication). This allows differentiated resource allocation across slices while sharing physical infrastructure, thus improving adaptability without proportionally increasing overall complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic resource allocation through network slice management functions that can dynamically provision, configure, and adjust resources based on real-time application requirements and network conditions. This enables the network to adapt flexibly to diverse services while maintaining manageable complexity through automated control mechanisms.

Inventive Principle:
Principle #15Dynamics

2Reliability

If network functions are centralized, then network control is simplified, but latency for location-specific applications increases

Engineering Contradiction:
Improvelatency performanceVSAvoidnetwork function distribution complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by enabling network slice functions to be deployed at specific geographical locations or network edges based on application requirements. This allows location-critical applications (e.g., autonomous driving, industrial automation) to access nearby network functions with low latency, while other functions remain centralized, thus improving latency performance without requiring complete decentralization.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces a new dimension of network architecture by implementing multi-layered network slicing that operates across different spatial and functional dimensions. This allows simultaneous centralized control for management functions and distributed deployment for service-specific functions, resolving the contradiction between centralized simplicity and distributed latency performance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If network resources are dynamically allocated based on geographical position, then resource utilization efficiency improves, but network complexity and monitoring requirements increase

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidnetwork management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms through network slice management functions that continuously monitor network conditions, application performance, and resource utilization. Based on this feedback, the system automatically adjusts resource allocation across network slices to optimize efficiency while maintaining manageable complexity through closed-loop control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies self-service by enabling network slice management functions to autonomously provision and adjust resources based on predefined policies and real-time conditions. This automated self-management reduces the need for manual intervention and complex centralized control, thus improving resource utilization efficiency while keeping network management complexity at acceptable levels.

Inventive Principle:
Principle #25Self-service
